LAUNDRY MACHINE "bnnawm TaizZZ-whom it may concern:

Be it known that we, HENRY"S..JUDD' 21I1d HENRY PLE'rscH, citizens ofthe' Umted States, residing at Chicago, in the county of-Cook and Stateof Illinois, have invented ,a certain new and useful. Improvement inLaundry-Machines, -of --which the following is a specification.

Our invention relates to .laundry cleaning and dyeing machines and hasfor its object to, produce certain newand useful improvements therein.

It is illustrated in the accompanying drawings, wherein- Figure 1 isa.plan View of our machine with parts broken away; Fig. "2, alongitudinal-section on the line 2-2. of Fig. 1; Fig. 3, an endelevation of the supply side with-parts broken away; Fig. it, a detailofaxpart of the circulating system; Fig. 5,

A,.A are legs which support the frame ortion, which consists principallyof end bows A A, the longitudinal rods, A A with .the inclosing spacingtubes A A and the bottom cross pieces A". These, with other parts notspecifically described, constitute the frame of the machine.

inner-ends by a considerable distance as in- I below the falsebottomfltoward the lowest part of the tub. The sidesof the'tub arepreferably composed of exterior sheet metal with interior. boards Dmatched and grooved and preferably held in position by bolts D Withinthe tub is a falseperfoof any desired shape but mounted so as to leavean interval. D beinner surface of the E are retracting or tensionspringspro vided each at its outer end with one ofthe screw plugs B, oneof the-bolts B and'one i pivotally connected by the pin E to projectionsE on the hub E which is permanently and rigidly secured to the end ofthe tub and apertured to permit the'passage of the tubular trunniontherethrough.

The circulating system comprises the tubular trunnion Fwhich' enters thetub at the lowest part and is securely mounted in the bearings F F. Itterminates at itsouter end in a T F from which leads the discharge pipeF controlled by the valve F From the T also rises the supply pipe Fterminating in a T F from one end of which leads the water supply pipe Fcontrolled by the valve F From this T also leads the pipe F controlledby the, valve F to the T F whence leads the pipe F This pipe isconnected with the pump F by the pipe F controlled by the valve F or thepipe F controlled by the valve F". The pump is connected with the tank Fby the pipe F controlled by the'valve F or by the pipe F controlled bythe valve F The pipe F communicates by means of the T F and valve F withthe benzin tank F which is contained within the tank F the steam pipe Fbeing adapted to heat the contents of said tank by means of the coils F'k The pipe E controlled by the valve F communicates with a boiler or anyother suitable steam generating means to permit the introduction ofsteam into the tub. The pipe F 32 controlled by the valve F leads fromthe T F and discharges into the tank F Suitable stop valves areinterposed in these several pipes as may be necessary.

The safety valve G comprises the valve 4 member G, seat Gr and spring Gis provided with the screw-threaded pipe Gr to engage the hole G in theupper portion of the end wall of the tub, and discharges through thepipe G elbow Gr and pipe Gr into the atmosphere below the tub.

In Figs. 8 and 9 is illustrated-a pressure relief valve. The valvecasing H is screwthreaded in the hole H and is closed at one end by thescrew-cap H which-is provided with the bearing H for the valve rod Hwhich carries the valve member H and is supported at the other end bythe short bearing H mounted upon the arms H The spring H is locatedbetween the valve member H and the cap H The discharge pipe H leads fromthe valve to the edge of the tub.

In Fig. 3 is shown the plug H inserted in the place of the sleeve H. Thehook J provided with the corrugated surface J adapted to engage thecorrugated surface J 2 on the pivoted lug J 3 is adapted to engage thehandle J of the belt shiftinglever J The nut J engaging the slot Jprovides means for regulating the position of the hook member J. Thehook K pivotally mounted upon the frame is adapted to engage the lug Kupon the tub to hold it in the central position, and to engage the lug Kto hold the tub in tilted position.

It will be evident that while in our drawings we have illustrated anoperative device still many changes might be made in the shape, size andarrangement of the parts concerned without departing materially from thespirit of our invention. TVe wish, therefore, that these drawings beconsidered as in a sense diagrammatic and that we be not considered aslimited to the particular =1 arrangement shown therein.

The use and operation of our invention are [as follows :We provide a tubmountedupon a horizontal axis adapted to oscillate thereabout, aninclined bottom for the tub below a false bottom, a pipe entering thetub .at its lowest point and adapted to serve both as a supportingtrunnion or axle and as a means of ingress and egress for liquids to'and from the pipe. \Ve provide a perforated lining for the tub adaptedto correspond more or less closely with the shape of the tub, and to beremoved a certain distance.

from the exterior walls. 7 This lining and this false bottom acttopermit the motion of liquids through and around the clothes in the tubwithout clogging or interfering with the passage of material through thepipe.

.We provide a tank supplied with heating coils whereby the-material maybe discharged into thetub either hot or cold and discharging means fromthe tub to said tank; also means for introducing steam into the tub, anda further tank and piping and a pump whereby material may be forced 1ings and mount the valve very loosely uponthe bearings in order thatclogging and gumming up of the valve may not occur. The tub is actuatedby a lever driven by an eccentric rod, said lever connected with the tubby means of a spring. This spring is connected at the top end to a screwplug, a.

stud assin through this In and en a ing a rock iiut. This stud isdjustablf, i n the screw plug and all adjustments may be made withoutrotation of the rock nut. This enables us to do away with any undueprojection of the stud from the rock nut which would be exceedinglydangerous and inconvenient, and we connect the eccentric strap by meansof bolts and lugs and provide the eccentric rod with slots transversethereto whereby the position of the rod may be shifted with regard tothe strap.

We claim 1. A washing machine comprising the combination of anelongated, oscillatory tub having an opening at itsend substantially inline with its bottom, communicating with said end opening in the tub, atrunnion at the opposite end of said tub, a driving lever mounted uponone of said trunnions and flexibly attached to the tub near its top,retractile springs radially extended between the tub and the sustainingframe respectively, and an inlet pipe united with the hollowv trunnionwhereby liquid may be fed into and withdrawn from the extreme bottomportion of the tub.

2. An elongated tub having a flat top and a hollow trunnion sidescomprising two panels at an. angle one with the other and with the topand'a bottom comprising two panels making an obtuse angle one with theother, a perforated false lining for said sides and part of the top,said lining corresponding in shape with and slightly removed from thesides and the top, a perforated false flat bottom for the tub restingupon the actual bottom at the sides and removed from it at the centerand projections upon the bottom of the tub between it and the falsebottom, said projections angularly located and terminating at a shortdistance from the center line of the bottom. j

3. A tub having a fiat false bottom and an inclined bottom below saidfalse bottom, a plurality of slanting vanes between said bottom and saidfalse bottom, said vanes adapted to turn the liquid toward the center ofthe tub and an'outlet from the tub at the lowest point of said inclinedbottom.
